WebGenome-wide association studies (GWAS) represent an emerging method to identify important genes which modulate human disease. GWAS primarily focus on relationships between SNPs and disease characteristics (traits). Briefly, this method scans the genome for SNPs, and can analyze hundreds or even thousands of SNPs simultaneously. WebDetails. The NMISS function returns the number of missing values, whereas the N function returns the number of nonmissing values. NMISS requires numeric values, whereas CMISS works with both numeric and character values. NMISS works with multiple numeric values, whereas MISSING works with only one value that can be either numeric or character. but herford
